To all whom it may concern: Be it. known that 1, Aims ELLIS, a citizenofthe-United States, residing'at' Flourtown, the county of Montgomeryand i State of Pennsylvania, have invented a new a and useful Cartridge,of whichthe following is a specification. My invention is a productdesigned for use in blasting-operations and for military purposes.- Itcomprises novel containing means for explosives, attaining thedesideratuin'of holding and preserving such explosives so that they canbe placed readily, expandedin position so as to fill the aperture inwhich they .are to be detonated, and detonated with great force andcertainty due to prevention of waste, the full utilization of the gasesand the exclusion of water.

Particularly in blasting rock and ore, it is important to hold theexplosive together so that it can be inserted readily in drill holes orother cavities and expanded in position so as to fill the same,

plosives, danger of accidental explosions, and liability to theprevention of the desired explo'sives. There are many previouspractices.- glycerin often creeps or. is forced into crevices, escapesis exploded accidentallyv later in drilling. With'pulverulentexplosives, there is great .difliculty in use aside from elements ofdanger, as the cartridge, when split, allows the explosive to pour outand'cannot' be pushed. home in many cases. Inwetholes, the explosive isoften saturated with water so that it-cannot be' detonated.

My invention attains the desired and, avoids the objectionableresultsspecified by the provision of an expansible container that holdsthe explosive together and protects it from the action of water, thecartridgepreferably having .an' outer casing provided with means forsplitting it withelements of danger in for the explosive.- Y

The nature and characteristic features of myinvention will be understoodfrom the following description and the accompanying' drawings inillustration of specific forms thereofp p In the drawings, Figure 1 isaperspective the longitudinal crimps,

without usual loss of exdetonation by the action of water upon the 1 Forinstance, the nitrothe desired detonation and pulling on the member 4,the explosive 1 1s retained in form and without spilling by the outinjury to the expanslble inner container Fig. 4 is a transversesectionalview of the cartridge expanded in a hole; and Fig. 5 is p p p Ip 'Patented'Mar. 2'7, 191?.

jpplieation fled February}, 1916; 7 serial 76,096- i 3- is a perspectiveview of 'aside view of a modified construction with a section of theouter shell removed andthe expansible inner casing partially open.

The cartridge, as 1llustrated,.in Figs. ,1 to l: inclusive, comprises anexplosive 1 sealed within an inner container '2, preferably composed ofparafiined paper provided with folds or plaits 2", and having the sealedend tucks 2", this container being formed from a tube which.

may be seamless. r I I A sealed .shell or case 3 covers the container 2and holds it, together with the tained explosive, against expansion,until it is desired to use the cartrldge, thev shell preferably being ajointed or seamless tube between the containers 2 and 3,

loose ends 4* adapted to be grasped, whereby such outer container .candesired toinsert the cartridge.

As shown in Fig; 4, the explosive 1 may be held in a container 6provided with the lonitudinal crimps, folds or plaits 6 in the cm ofspirals, andcwith the perforations 6 which. are designedto aid insealing the longitudinal lap joint of the tube. A case orshell 7 sealsthe container 6 until it is desired to use the cartridge, vided with theperforations 7? for aiding the maln'ng'of a secure lap joint and wit hthe string 8 for splitting the wrapper when 1t is desired to use thecartridge.

3. A cartridge comprising an expansibie container for an explosive, a,case for. saici container, and a strandedapted for splitting 1o saidcase.

In testimony whereof I have hereunto set my name this 31st day ofJanuary, 1916.
